. IMPROVEMENT IN CLOTH-FINISHING MACHINES.

j i I Specification forming part of Letters Patent No. {8 0,705, dated Augu'stB, 1876 application filed .April26,1876. v A

To all whom it may concern:

Be it known that I, CALEB S. DAVIS, of Manayunk, in the city and county of Philadelphia, in the State 'of Pennsylvania, have invented certain Improvements in Cotton-Cloth- Finishing Machines, of which the following is a specification:

This invention relates to several improvements in a certain machine for finishing cotton goods, for which Letters Patent were granted to me, dated January 24, 1860, No. 26,895; and consists in the mode of regulating the tension of the goods against the several brush and emery rollers, by introducing slotted bars or rollers between the several pairs of rollers,

and acting in unison with each other, together with the addition of a frame with slotted bars to prevent wrinkling, and to deliver the goods to the action of the brush and emery rollers more evenly, as well as the weighted bearings for the windingup roll over the calenderin g-cylinders.

The accompanying drawing, with the letters of I reference marked thereon, and a brief explanation, will enable those skilled in the art to make and apply the several improvements.

Figure 1 is a side elevation, to show the position of the coupled ratchet-wheels, with their pawls. Fig.2 shows the other side of the machine, and the position of the strap-pulleys;

.Figs. 3 and 4, the end views of the machine.

Fig. 5 illustrates the relative position of the brush and emery rollers and slotted adjustable tension-bars; Fig. 6, a perspective view of one of these slotted bars, ratchet, pawl, and connecting-bar suspended to it.

The combination of the steam-calender with self-acting steam-cylinders K L is substantially the same, as also the frame-work A and general internal arrangement of the machine, as in my former patent, and these require no special notice. I therefore confine my description to the improvements already intimated,

viz:

I add an extension, B, terminated by two elevated upright posts, 0. These form a bearin g at top for a traction-roller, 0, and are also united by slotted cross-pieces m n. The latter are provided with sliding clamps, to gage the width of the slot to the cloth, which is passed through said slots upward in full view of the attendant. From these it passesover the traction-roller 0, down again through said slots to the lower carrying-roller Q, in order to prevent any creasing or folding, and to present the cloth smoothly to the action of the emery and brush rollers formerly used.

As cloth varies in thickness, and for producing more or less contact with the several rollers, and to produce various results in the finish of cloth, I have introduced two slotted tension-bars, R B, one vertically over the other, and diagonally between the pairs of emery-rollers 1 2 and brush-rollers 3 4, as shown by Fig. 5. The cloth being passed through the slots in said bars, andbetween the several pairs of rollers mentioned, to the upper carrying-roller Q it is carried to the calenderiug-cylinders.- These slotted bars R R are so arranged that when the slots in them are in a vertical position the cloth comes but slightly in contact with the several pairs of dress-rollers; but when more or less inclined, the cloth is more or less brought against the action of said emery and brush rollers. Thus the friction can be increased to any degree, according as the slots in the rollers vary from the vertical to the horizontal position, giving a range of ninety degrees for adjustment.

To hold them in their adjusted position, they (the said bars R R) are provided with ratchet-wheels or segmental wheels H I, engaging with pawls pivoted to the side frame, and joined in their action by a pivoted connecting-rod, 01;, so that when one of the bars is turned the other turns in unison with it.

This arrangement, in combination with the emery and brush rollers, allows the most accurate adjustment to be made, and the desired amount of friction to be obtained, as circumstances may demand. Besides, a very soft finish or nap can be given on both sides of the' ure upon the bearings or shaft of the windingup roller 10, above the cylinder K. The slotted uprights D, in which the several bearings of the cylinders K L are adjusted, have a top bracket, d, for a rod, E, bent at two points,

c n gueustv at gh angl s- !D-he e t s legs are new and guided "insaid ibra clget 91;, these legs being parallel. One is provided with a flat bearing-bar, f, which sets ox er the end of the-shaft of the roller is, one on each Side f the machine, The ther legis pr -sided witha'weig-ht, 'lhis Weigh-t isadfjusted so as to cause the plate f to keep the desired tension on the winding-n9 pol-Len 19 as it in.-

creases in bulk, and yet" so as to yield during .n.cloth-ro ll K over the bearings of the calenderits augmentation.

t e e i p o ements, lde v t my for mer invention I no-wjiave made it a veryfvalu. able machine, by which new and useful results 1 are produced, and said improvements SllbSliflQ-h tiall y changing the same to a new coinbina tion'. Hence, i
